Question: I have a problem with the audio quality using INOGENI 4K2USB3 4K HDMI to USB 3.0 Converter on a computer that is running Windows 7. There is a lot of random audio noise during audio playback. Computer hardware. (Intel Core i5-3470 CPU 3.20 GHz, 8GB RAM, 64bit OS )
Answer: I suppose that your microphone level is at 100%. You can check by doing a right click on your volume icon at the bottom right corner and select Recording devices, choosing the Recording tab, right click on the INOGENI device and select Properties. In the Level tab, you can change the level to an optimal one in order to cancel the noise. Attached is a custom firmware that you can use with the INOGENI Control App. It will change your audio device to a standard “Digital audio interface” instead of a microphone. Input level will be acceptable even at 100%. This digital audio interface will be added to the next official firmware release.
